摘　　要：考虑量测噪声和地球曲率对配准的影响,提出了一种基于地心坐标系(ECEF)的扩展卡尔曼滤波(EKF)配准与目标跟踪算法。根据坐标系转换关系,给出误差配准计算公式,建立目标的动态方程,用EKF方程进行估计。仿真结果表明:该法能同时有效估计目标运动状态和传感器配准误差,可用于远距离的传感器配准和目标跟踪。An extended Kalman filter(EKF) algorithm based on earth-centered earth-fixed coordinate system was put forward when the measurement noise and the geometry of the global were considered in this paper.According to the formula of co-ordinate conversion,the align algorithm and the dynamic model were developed,and the EKF method was used to estimate both the registration errors and system states simultaneously.The simulation results showed that this algorithm could be used for the registration and tracking betwe...
